Abstract: Method and apparatus for reducing call setup time for calls to Advanced 800 customers by eliminating one database query. (Toll charges for 800 calls arepaid by the called customer.) In the prior art, a call to an Advanced 800 customer required accessing a Basic 800 database, then, using data obtained therefrom, accessing an Advanced 800 database. In accordance with this invention, a table of the most frequently called Advanced 800 numbers and the corresponding data normally obtained from the Basic 800 database is dynamically maintained in each toll switching system. When an 800 call is received at a toll switching system, the table is examined to see if the Advanced 800 service accessing data is stored therein. If so, the advanced 800 database is directly accessed without first accessing the Basic 800 database; if not, the call is processed as in the prior art, plus updating the table if the call is to an Advanced 800 customer. Advantageously, such an arrangement reduces call setup time to frequently called Advanced 800 customers by about 1.5seconds.

Abstract: ABSTRACT           A circuit for controlling bi-directional operation of a vehicle window lift motor having a toroidal coil sensing counter-emf perturbations in the motor current line.  An EXPRESS mode switch, upon momentary actuation, latches an electronic switch to operate a relay to provide continuous motor rotation for lowering the window.  Subsequent momentary switch actuation unlatches the electronic switch to cut interrupt window motor current.  Window lift motor stall is detected by a toroidal coil which senses loss of motor line perturbations and unlatches the electronic switch to open circuit the motor relay.

Abstract: A ribbon cartridge for an endless ribbon used in high speed printers, with increased reliability due to fewer parts,  is  constructed  from a molded  casing which  is rectangular in shape into which are formed a post on which a cylindrical porous ink reservoir is mounted,  a ribbon protector which isolates the ink reservoir from the ribbon in the stuffer box portion of the cartridge, and a forked bracket for mounting a shaft on which gears are mounted.   A combination gear for driving a ribbon into the stuffer box and for re-inking the ribbon is mounted on a post  and then rotatably mounted on the bracket formed into the housing and is inked by contact with  the  ink  reservoir.   An  idler gear is  rotatably mounted on a bracket which is pivoted from a  socket molded into the socket wall and is spring biased into contact with the drive and transfer gear, which is turned by its extended shaft advance and ink the ribbon.  As a result  a  simplified re-inking arrangement  is  achieved with the minimum of components.   Also,  by re-inking a central drive and transfer gear, only the print track of a ribbon is reinked thereby extending the re-inking life by conserving ink.

Title: Process of recovering sulfur from sulfide materials which contain thermally releasable sulfur
Inventor: FITTING ARNO
IPC: C01B17/06
Filed: 1990-07-26
Abstract: ABSTRACT     For a recovery of elementary sulfur from sulfide materials which contain thermally releas-able sulfur, the sulfidic material is charged to the top portion of a fluidized bed reactor of a circulating fluid-ized bed system. Oxygen-containing gases and SO2-contain-ing, recirculated gas are fed to the bottom portion of the fluidized bed reactor and the oxygen rate is so controlled that it is sufficient to oxidize the iron content of the sulfidic materials and to meet the heat demand of the process in that a  part of the sulfur which is supplied is oxidized to SO2. In the intermediate zone of the fluid-ized bed reactor, elementary sulfur is formed from sulfide sulfur and SO2 under reducing conditions. The thermally releasable sulfur is released in the top portion. A major part of the solids contained in the suspension leaving the reactor is  separated and recycled to the reactor. Elementary sulfur is recovered from the ex-haust has and part of the SO2 content is discharged and the remaining part  is  recycled as fluidizing gas to the reactor.

Abstract: SYSTEM FOR ORIENTED STRAND LAYUP          ABSTRACT OF THE DISCLOSURE       A system for continuously forming a multi-layer, oriented strand layup from at least two, and preferably four, layup feed sources. At least first and second layups are simultaneously formed, overlapping one on top of the other in zig-zag patterns on a longitudi-nal, sid-to-side moving conveyor trough. The top of the bottom layer is formed at the same time as the bottom of the top layer, and an angled base on which the strands fall is thereby created which has a consistent strand angle across the interface of the layers. This care-fully coordinated layup motion forms a strand mat with a continuous average strand angle throughout its layup feed interface(s), thereby forming, after heating and compression thereof, an elongate compos-ite product having consistent strength properties.

Filed: 1990-08-14
Abstract: ABSTRACT      A process for the liquefaction of natural gas is disclosed wherein expansion valves for low-level multicomponent refrigerant and liquefied gas product streams are replaced with process-loaded turboexpanders having liquid inlet streams.  Each turboexpander is coupled with a compressor or pump so that expansion work extracted from a given stream is used directly to compress or pump the stream prior to cooling and expansion.  The use of process-loaded turboexpanders reduces the minimum work of liquefaction and increases the liquefaction capacity of the process.

The first film 1 is bonded to the second film 6 over a portion of the films projecting laterally outwardly beyond the rim of the tray 5.  The multi-layer structure of the first film 1 has a bond 4 of low bond strength between a thin upper part 3 and a relatively thicker lower part 2 thereof.  Thus the second film 6 and the upper portion 3 of the first film 1 can be delaminated from the remainder of the first film 1 and can be ruptured by penetration of the upper portion 3 by the corner of the rim of the tray 5.  This delamination is assisted by a cut 7 in the bottom film extending diagonally across a corner of the pack.

IPC: H02P9/42
Filed: 1990-09-19
Abstract: ABSTRACT OF THE DISCLOSURE         A control system for an AC exciting synchronous machine for use in an electricity generator/motor system.       The AC exciting synchronous machine can be driven not only in a variable-speed operation based on 2-axis current control but also in a constant exciting frequency operation based on only direct-axis current component control.  A phase signal is switched to drive stably the AC exciting synchronous machine in a self-excited operation or in a rotary phase modifying operation.          Further, when it is desired to start pumping-up water, a synchronizing power is provided to keep constant the rotational speed of the machine at the time of establish-ing a desired water pressure.  Because of such switching arrangement of the phase signal, the AC exciting synchronous machine can be operated as an ordinary synchronous machine exhibiting ordinary synchronous characteristics, that is, self-excited operation charac-teristics, rotary phase modifying operation character-istics and pumping-up start characteristics.  Even when the synchronous machine is cut off from an AC power system and the voltage of the synchronous machine is abruptly changed, the stable self-excited operation of the machine can be realized.
